WINIDGW VENTILATOR.

Application filed March 22, 1928. Serial No. 263,693.

This invention relates to improvements in ventilators generally, and more particularly to ventilators for windows of buildings and the liken The principal object of the invention is to provide for a ventilator of a comparatively simple and inexpensive construction, and one adapted of being readily and easily secured in position exteriorly of a window casing and arranged in cooperative relation with either of the upper and lower sashes of a window, or both, as may be desired.

Another object of the invention is to provide for a ventilator as characterized, and one which may be permanently positioned outside of a window casing without in any way interferring with the cleaning of the outer sides of the sash glass, or with the use, removal or replacement of screens employed at the outer side of the sash.

With the foregoing and other equally important objects in view, the invention resides in the certain new and useful construction and arrangement of parts as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a window showing a practical application of the ventilator thereto,

Figure 2 is a horizontal section taken on the line 2 2 of Figure 1,

Figure 3 is a perspective view of one end of the top section and a pair of the complemental end or side sections of the ventilator frame in relative positions for assembling,

Figure 4 is a vertical longitudinal section through a window and an associated ventilator, and showing an alternative association of the ventilator with either of the upper and lower sashes of the window, and

Figure 5 is a view similar to that in Figure 4, and showing theventilator as associated with the upper sash of the window L with a movable or removable outer screen associated with the entire window opening of the casing. l Y l Referring to thev drawings, wherein similar characters of reference designate corresponding parts throughout the several views thereof, a and ZJ, Yrepresent the opposite vertical kside kmembers or styles of a window casing or frame, c the top or head member of the same, d the sill thereof, and e and f the upper and lower sashes repectively mounted for vertical sliding movement in the parallel channels or grooves arranged on the opposed inner faces of the styles a and b4 for their reception.

The ventilator, as constructed and arranged in accordance with the'present invention, comprises oppositely disposed outer side members 10 and 11 and similarly disposed inner side members 12 and 13 respectively, complemental to the outer side meinbers. These several side members 10, 11, 12 and 13 are each substantially triangular in plan, and are preferably formed of a suitable gauge sheet metal. The outer side members 10 and 11 are identical one with respect to the other, and have their inner vertical side edges outturned to provide supporting flanges having spaced openings in the same for the engagement therein of suitable fastenings 14 by means of which the members are to be secured in position at the outer opposite sides of the window casing or frame, while the outer and upwardly and inwardly inclined side edges thereof are similarly inturned to provide flanges 10 and 11 to engage the outer side of the opposite side edge portions of a front wall 15 extending between the outer members 10 and 11. v

The inner side members 12 and13 are also identical in form one with respect to the other, and are arranged to be secured against the inner wall of the outer members 10 and 11 by means of fastenings 16 engaged through. vertically spaced sets of aligned openings formed in the abutted portions of the several members for the purpose. The outer upwardly and inwardly inclined front edges of these inner members 12 and 13 are inturned to provide flanges 12l and 13 respectively, which lie in spaced parallel relation to and directly in rear of the similarly 'inturned flanges 10` and 11 at the outer side edges of the outer members 10 and 11, and engage the inner side edge portions of the front wall 15.

With the opposite side edges of the front wall 15 engaged inthe channels formed between'the'complemental flanges 10 and 12 and 11.. and- 13 of the pairs of associated side members 10, 12 and 11, 13 respectively, the top yedge of the same is disposed in the plane of the upper evenly disposed endsvof the said side members, while its lower edge is spaced upwardly of the lower ends of the latter. To effectively support the front wall 15 in this position, the inturned flanges 12 and 13, of the inner side members12 and 13, are severed in the plane of the lower edge of the front wall 15 and the lower portions 12 and 13 are projected outwardly from and in the plane of the wall portions of the side members 12 and 13, which are abutted against and secured to the complemental wall portions of the outer members 10 and 11, whereby these lower portions 12 and 13" extend forwardly across the channels and engage beneath the lower edge of the front wall 15 in supporting relation thereto.

If the ventilator, as thus constructed and arranged, is to be employed in conjunction with the upper sash e, the same will be positioned with the top edge of the front wall 15, and the upper ends of the several side members 10, 11, 12 and 13 disposed substantially in the plane of the top face of the head or upper cross piece c of the window casing or frame, and with the outturned flanges 10 and 11', of the outerV side members 10 and 11, abutted against the outer side edges of the vertical members or styles a and t respectively of the window casing or frame, when the fastenings 14 will be engaged in the latter after being inserted in the vertically spaced openings formed in the lianges l and 11 for the purpose.

To complete the effectiveness of the device for Ventilating purposes, and to cause the same toprotect the enclosed portion of the window from rain or snow during inclement weather, a shield 17, preferably in the form of a strip of sheet metal of a length equal to width of the ventilator, and, con-' sequently, of the window casing or frame, is laid over the top edges of the upper ends of the several side members 10, 11, 12 and 13, and the top edge of the front wall 15 and has its front edge turned downwardly to provide a flange 17 engaging the outer side of the top edge portion of the front wall 15. The rear or inner edge portion of this shield 17 is preferably inserted for a distance inwardly of the top surface of the head or upper cross member c of the window casing or frame, and between the same and the overlying portion of the wall of the building in which the window may be incorporated. Thus, with the shield 17 so engaged in position, and with the front wall 15, of the ventilator, declining or sloping in a downward direction and outwardly from the window, water and snow will be effectively directed away from the latter for practically its entire height.

Referring more particularly to Figure 4 of the drawing, while the ventilator is preferably employed for use in conjunction with the upper sash e of a window, in which position the same is shown in full unbroken lines, it is within the purview of the invention to make use of the ventilator in conin certain instances,

junction with the lower sash j of a window, and to this end, the outturned flanges and 11, of the outer side members 10 and 11, will be secured to the side members or styles a and Z2, of the casing or frame, in the same manner as before, with the ventilator so positioned with respect to the lower sash 7 that the upper ends of the several side members 10, 11, 12 and 13, and the top edge of the front wall 15 of the same will be disposed in the plane of the top edge of the lower rail of the upper sash e, when the shield 17 will be positioned to overlie the upper side of the ventilator, as in the first instance, but with its rear side edge abut ting the outer surface of the upper sash glass, substantially as shown.

Referring now to Figures 4 and 5, a full length screen g is shown in a usual position at the outer side of the window casing or frame, and, with the ventilator secured in position at the upper side ofthe latter, the angle of inclination of the front wall of the ventilator is such as to give a su'icient clearance between its inner side and the plane of the outer side of the window to admit of the outward swinging of the lower end of the screen g to allow for its complete removal from engaged position at the front side of the window casing, or to allow it to be sustained in an outwardly inclined position, corresponding to the inclination of the front wail 15 of the ventilator, whereby the exterior surfaces of the glasses of both the upper and lower sashes e and 7 may be readily cleaned, as will be apparent by reference to Figure 5.V

As shown in Figures 3, 4: and 5, the screen 8 is to be fitted into the window casing or frame at the outer side thereof, and the same may have a latch member k at the inner side of its lower end, which, when released, allows the screen to be swung outwardly of the casing or frame to a position whereby the arms of a person may be extended outwardly of a sash opening for the cleaning of the outer surfaces of the sash glasses.

The front wall 15, of the ventilator, may be of any desired sheet or plate material, either opaque, translucent or transparent, but, asl shown, is preferably of glass, whereby the full normal lighting effect to the interior of the building through the window will not be appreciably impaired. However, it may be desirable to have the inner surface of the front wall, when of glass, frosted, as at 18, which frosting may extend across ythe upper side portion only of the said inner surface of the front wall 15, as shown in Figures l and 5, or over the entire area thereof.

To permit of the use of interior shades or curtains with a ventilator of this character, suitable brackets 19 are` preferably attached, as at 19, direct-ly at the inner side of the top rail of the upper sash e, whereby, when this sash is in its lowered position to give full Ventilating etfe'ct to the interior of a room, the brackets 19, and the curtain or shade carried thereby will be lowered with it, in which case, the curtain or shade will then be cooperative with the lower half of the window.

vWith the ventilator associated with either the upper or lower sashes e or f of a window, by lowering the upper sash e, on the one hand, or raising the lower sash f on the other hand, ventilation of the interior of a room, building or the like will obtain, and by varying the width of the openings of the sashes, various Ventilating etects will be correspondingly had.

lVithout further description, it is thought that the features and advantages of the nvention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.

Having thus fully described the invention, what is claimed is:

1. A ventilator comprising substantially triangular shaped side members adapted to be supported in position at opposite sides of a window casing, a front wall of a transparent material extending between the outer inclined side edges of said side members, with its top edge disposed in the plane of the upper ends of the latter, and a shield overlying the upper ends of said side members and the top edge of said front wall.

2. A ventilator comprising substantially triangular shaped side members adapted to be supported in position at opposite sides of a window casing, a front wall extending between the outer side edges of said side members with its top edge disposed in the plane of the upper ends of the latter, and a shield overlying the upper ends oi said side members and the top edge of said front wall.

3. A ventilator comprising substantially triangular shaped side members and adapted to be supported in position at opposite sides of a window casing, a front wall extending between the outer side edges of said side members with its top edge disposed in the plane of the upper ends of the latter, a shield overlying the upper ends of said side members and the top edge of said front wall, and a portion depending from the outer side of said shield and engaging the forward side of the top edge portion of said front wall.

4. A ventilator comprising substantially triangular shaped side members adapted to be supported in position at the opposite sides of a window casing, spaced parallel flanges arranged on the inner sides of said side members immediately adjacent the outer side edges thereof and forming channels, a front wall extending between the said side members and having its opposite side edges engaged in said channels, means extending across the lower end portions o' the said channels to support the lower edge of said front wall, a shield overlying the top ends of said side members and the top edge of said front wall, and a flange depending from the front edge of said shield and engaging the outer side of the top edge portion of said front wall.
